Connectivity in Japan
Network coverage
NTT Docomo and SoftBank provide the backbone. Coverage is strong across Tokyo, Osaka, Kyoto, and the Shinkansen corridor. Rural Hokkaido and smaller islands can drop to 3G in spots, but cities and transit are consistently LTE or 5G.
Arrival tips
Install before you land - Narita and Haneda immigration queues are long and you will want Google Maps working the moment you clear customs. Suica and Pasmo transit cards are phone-native now, so having data from arrival means tap-to-ride from the airport train.
Plan recommendation
A 7-day 3-5 GB plan covers a standard Tokyo-Kyoto week. If you are streaming on Shinkansen rides or tethering a laptop, go 10 GB or higher. Two-week plans suit the classic Japan Rail Pass itinerary.

Why use an eSIM in Japan
- Cheaper than roaming
- Carrier roaming bills a daily fee whether you use data or not. A prepaid plan bills once, upfront.
- Working the moment you land
- No hunting for a shop, no passport registration, no airport queue at midnight.
- Your number stays yours
- Dual SIM keeps calls, texts, and WhatsApp on your home line while data rides on Jelly.
Getting online in Japan
Buy a plan and scan the QR code from your email while you still have Wi-Fi.
Land in Japan, switch the Jelly line on, and set it as your data line.
Turn off data roaming on your home line so your carrier cannot bill you.
Postcards from our travelers
Installed the Japan plan on the train from Narita. Maps and my transit app were live before I reached the hotel, and it cost less than one day of my carrier's roaming.

Japan eSIM questions
When does my Japan plan start counting?
Validity starts when the eSIM first connects to a network in Japan, not when you buy it. Installing early costs you nothing.
Can I make calls in Japan?
Jelly plans are data plans. Calls work over WhatsApp, FaceTime, or any app you already use, and your home number stays reachable on your other SIM.
Can I tether a laptop in Japan?
Yes on most compatible phones. Tethering uses data quickly, so pick a larger plan if a laptop is coming with you.
What if I run out of data in Japan?
Top up from your dashboard. The top up applies to the eSIM already installed, so there is nothing new to scan.
